Please help :D > > Fabio > The OpenJDK package itself is no different to the one that's been in earlier versions of Fedora since January [0] [1]. I believe GCC 10 is the issue here. It has taken a significant effort to even get java-1.8.0-openjdk to build with GCC 10 [2], mainly by turning off a number of optimisations, and a backlog of changes has built up. We really need to be getting these packages updated for the next security update this time next month. Do you know if F32 & rawhide are using the same GCC?
